ZMQ::LibZMQ2 build fails

[wsdookadr]

What I tried

I very much appreciate and sympathize with the efforts made towards developing this module.

(I am not 100% sure if I should post this bug report as ZMQ::LibZMQ3 is out and maybe I should try that instead)

I'd like to report a problem.

I am running Perl 5.14.2.

I will describe all my install attempt: I first ran git clone git@github.com:zeromq/libzmq.git to get the source for 0MQ.

Then I installed it to my $HOME with ./autogen.sh ; ./configure --prefix=$HOME/local; make; make install;

After this I added these lines to my ~/.bashrc so that:

• the header will be automatically detected by gcc

• the library will be found by gcc

• pkg-config is able to find the libzmq.pc

  export C_INCLUDE_PATH=$C_INCLUDE_PATH:$HOME/local/include
  export CPLUS_INCLUDE_PATH=$CPLUS_INCLUDE_PATH:$HOME/local/include
  export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:$HOME/local/lib/pkgconfig

Now I'm going to try to install ZMQ::LibZMQ2 from CPAN like this cpanm ZMQ::LibZMQ2 , however, I am getting this:

Detected the following ZMQ settings:
 + ZMQ_HOME = (null)
 + ZMQ_H = (null)
 + ZMQ_INCLUDES = 
 + ZMQ_LIBS = -L/home/user/local/lib -lzmq  
 + ZMQ_TRACE = (null)

So I thought, ok I will give it what it needs(I am unsure if I did this right):

ZMQ_HOME=/home/user/local/lib/ \
ZMQ_H=/home/user/local/include/zmq.h \
ZMQ_INCLUDES=/home/user/local/include \
ZMQ_LIBS=/home/user/local/lib perl Makefile.PL

The result

Questions

Is ZMQ::LibZMQ2 still recommended or should ::LibZMQ3 be used instead ?
If ::LibZMQ2 can still be used, what libzmq version should it be used with ?

Well, I can't say I know /all/ of its guts, but I suspect that it's just that MakeMaker (which does the REAL magic to compile the XS extension) just don't support those env vars.

One thing I noted was, if you have all the zmq stuff under /home/user/local, then you should be able to do

ZMQ_HOME=/home/usr/local perl Makefile.PL

If you do the above, tools/detect_zmq.pl (called from Makefile.PL) basically just checks if $ZMQ_HOME/include, $ZMQ_HOME/lib exists, puts them in the paths, and see if compilation works.
